BOFH, I'm confused - I've been running various Linuxes for about 5 years and never encountered or had to use JCL when installing drivers or otherwise - usually there's a binary driver available but occasionally I've had to compile from source - never needed JCL.
AKAIK Job Control Language (JCL) is a means of communicating with the IBM 3090 MVS Operating System.
Google tells me that JCL consists of control statements that:
* introduce a computer job to the operating system
* request hardware devices
* direct the operating system on what is to be done in terms of running applications and scheduling resources
So sorta like a script (batch language for DOS old-timers) and JCL scripts can be converted to Korn or Bash scripts.
What has this got to do with installing device drivers in Linux?
If I've never needed to use JCL scripts in fiddling with Linux for quite a while, then what am I missing (and what if Keef doing that needs 'em)?
Ahhhh DOS!
